A bookmaker token that lets you place a bet without risking your own cash, with the stake usually not returned in the winnings.
If a free bet wins, you keep the profit but not the token stake itself, so a 10 free bet at 2.00 returns 10, not 20. Free bets are common in welcome offers and carry their own terms. They sit at the heart of matched betting. Used well, free bets fit a wider plan; see our betting strategy guide.
